Ds is 6 and just came out of the bath and we noticed one testicle is swollen and very veiny / bluey looking and the other is maybe shrunken but not sure if this is just in comparison to the other iyswim? He doesn't say it hurts and obviously it's possible it's been there a few days.
Bit worried - wwyd? Also worrying about in case it's a malignant tumour :(
